    Please help normal distribution? student t distribution? or neither?

    Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, student t distribution, or neither.

    Claim ,u=78

    sample data
    n=24
    x=101
    s=15.3

    The sample data, for this simple random sample, appear to come from a population with a distribution that is very far away from the normal, and o~ is unknown.

    If the raw data does not come from a normal population the mean itself may still follow a normal distribution.

    Therefore in your case use a t-distribution as the population standard deviation is not known.
